Hi, so i tried to change the original SwB 2 position switch with a 3 position. The swap and soldering was easy and straightforward. But as soon as i went to display to test it, i discovered that...
Up position shows 1000(low),
Middle position shows 2000(high),
Down position shows 1500(middle),
Middle and down are inverted. That doesnt seem logical to me.
So i did a very little change of the provided schematic and now the 3 position SwB behaves as it should like SwC.
So the 4.7k resistor goes from middle pin to ground, and the top pin goes straight to 3.3v, as shown in the picture. Simple as that! Seriously, i dont know why hasnt someone recommended this.
